Question

An octopus has .

• A. hearts
• B. eyes
• C. arms
• D. all of the above

Hint:

Consider the circulatory, visual and limb related anatomy of an octopus.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The question lists three body features, hearts, eyes and arms, and asks which of them an octopus actually has.

Step 2: Key Approach:
Go through each feature one at a time and check it against known octopus biology.

Step 3: Detailed Explanation:
An octopus has three hearts in total. Two of these push blood through its gills to load it with oxygen, while the third circulates that oxygen rich blood around the rest of its body.
It also has a pair of camera type eyes that let it see shapes, light and movement in its surroundings.
In addition, it has eight muscular arms covered in rows of suckers, which it uses for crawling, grabbing prey and handling objects.
Since each of the three features, hearts, eyes and arms, is confirmed to be present in an octopus, none of the first three options alone captures the full picture.

Step 4: Final Answer:
Because an octopus truly has three hearts, eyes and eight arms, the complete and correct answer is all of the above, option (d).
